X::Proc::Async::AlreadyStarted Reference

Error due to calling start on an already started Proc::Async object

What it is #

Examples, run three ways #

Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.

Not executed: the documentation states no expected output for this example.

my $proc = Proc::Async.new("echo");
$proc.start;
$proc.start;
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Proc::Async::AlreadyStarted: Process has already been started␤»
